I don’t think that we’ll find any dinosaurs hidden in some remote jungle. The main reason for this is that while new specifies are found all the time, they are genetically fairly closely related to known animals. That an animal genetically so distinct as a dinosaur could have survived in a small ecological niche for such long period of time doesn’t seem likely.
However, as to the ancestors of dinosaurs, birds are pretty common! My understanding is that birds are thought to have evolved from a dinosaur ancestor, so in this sense the descendants of dinosaurs are very much with us.
No Emily, sadly I don’t. They did all become extinct, which is sad because my two boys love dinosaurs!
Some of the later dinosaurs were starting to resemble early birds and it is likely that evolution allowed these birds to develop into the birds we know today. What we also know is that the loss of the dinosaurs, which really did rule the world millions of years ago, allowed for the growth, development and evolution of the mammals, which became a large dominant species. Don’t forget though, that we still have crocodiles which are the closest relative we have of the dinosaur and they can live of long periods.
Hi again Emily,
I believe that there are still dinosaur fossils, and plenty of them! If you mean dinosaurs in terms of evolution, I think that you can draw a lot of links between some animals that we see on a regular basis now and dinosaur fossils that have been discovered. If for example you look at the skeleton of a chicken and compare it to that of a T-Rex, you will find they look remarkably similar! This topic however is hotly debated, with a lot of scientists believing that birds have evolved from maniraptors; a breed of small dinosaur. As to what I believe, I think this sounds plausible – there are a lot of dinosaurs that bare a striking resemblance to birds (including the velociraptor!)
